3.1. Components of the RC Switch with Small Low-Side MOSFET
Pololu RC Switch with Small Low-Side MOSFET, top labeled view.
The Pololu RC Switch with Small Low-Side MOSFET has 11 through holes spaced 0.1″ apart that fit
0.1″ header pins.
RC interface
The GND, VRC, and RC IN pins make up the switch’s RC interface and can be connected directly to
an RC receiver or servo controller:
• The GND pin is the ground or reference voltage.
• The VRC pin connects to the RC power line. The power from VRC is not used by default, but
a jumper on the bottom of the board can be bridged with solder to power the board from VRC
as described below.
• The RC IN pin is the RC signal input. The switch measures the width of pulses on this line
and uses that to decide whether to activate or not.
